The table shows Eric's work when solving the equation x
- 8x - 65 0.
Step
Given
Step 1
Step 2
Step 3
Step 4
Step 5
Step 6
Equation
x2 - 8x - 65 = 0
x2 - 8x + 16 - 65 + 16 = 0
(x-4)2 - 49 = 0
(x - 4)2 = 49
x -4 = +7
x = 7+ 4 and x = -7 + 4
x = 11 and x = -3
In which step is Eric's work incorrect, and why?
